I have not driven this car in almost 10 years and it was nothing like it is now. I am a bit concerned about my lead foot and my girlfriend is actually a bit scared to ride in it.  popcrn

It's a RB (440) block. You can see the machined pad on the front left side of the block.

Completely unsilenced big bore motor, dynoed outside (effectively!)  noise and fumes just venting to the outside world. That shop must be real popular with the neighbours!! Never seen a dyno over hear that wasn't in a sound deadened room with exhaust extraction and filtration and safety guards in case of catastrophic rod or flywheel failure and the operators behind the glass! You Americans and your fun attitude to heath and safety! Long may it continue...LOL!

Yes, I have around 3500 miles on it as of now, drives great! With 3:23 rear gears I can cruise at 70 all day and light them up at will.

I've only owned stock Mopars.  I'm not used to driving 500HP cars.  I see people commenting on stroker builds with comments like "Dual plane, 850CFM, tiny 1-3/4" headers? Jesus, put a cork in it, why don't you." "You need at least 250@.050", or it'll fall on it's face."  "You need solid cams if you want to make power."

You got a dual plane, 850cfm carb, 1.8" headers, and 235 @.050" hyd. roller cam.  Are the RPM heads the smaller Edelbrock heads?  I see so much hate on "tiny" specs like this, on other posts, and you're making 580 HP @ 5400 RPM and 660 TQ @ 3900 RPM!  Those look like outstanding numbers to me.  How can this not be a blast to drive?
